a 3 Wm wtoz -3 55a PeiEe/mann 13 Luqbtozme 1 4 I member 22 has aplate-like body with feet 2% at an angle thereto in which are openingsScrews 26 have their bodies passing through the openings 25 and serve torigidly hold the hangers to the supporting plate 11 of the frame. Thehanger member 22 is provided with an annular rib 27 formed by depressinga portion of the body thereof, and resting directly against said rib isan annular rib 28 of the type-bar 16. The typebar 16 has an enlargedhead or boss 29 and may also have its rib 28 formed by depressing a partof the head 29' in the manner shown. The type-bar has its rib 28 opposedto the rib 27 so as to form an annular space or chamber 30 in which asuitable lubricant may be placed if desired, and said type-bar has itshead located in the space 31 formed between the hanger members 22 and23. By providing the ribs a large substantial hearing surface withlittle friction is provided, and said bearing surface may be readilyground to provide suitable surfaces instead of grinding the entire facesof the hanger member and the type-bar head.

The member or strap 23 of the hanger may be made of lighter metal thanthe member 22 and may be of spring material and has one end, as 32,provided for an aperture through which passes the body of the 'screw 33,in order that said member 23 may be held to the member The member 23 atthe end may als be provided with depressed parts, as 3 t, forming dowelpins which are adapted to enter recesses 34 in the member to assist inholding the member 23 against swinging movement and in proper positionrelative to the member 22. This member 23 is offset at to provide thespace 31 for the type-bar hos and has a vertical portion from which mybe depressed a substantially scmi spherical member or body 37. The body37 is located at the free end of the member and performs the samefunction as a ball pivot except that it is immovable in a rotarydirection, and said body 37 is adapted to be seated in a conical orcup-shaped recess or opening 38 formed in the type-bar head or boss 29.The recess or opening 38 tapers from the outside of the type-bar inwardand is so arranged with respect to the member 37 that a hearing or pivotfor the type-bar is provided at one point and that on the side oppositethe member 22 of the hanger or support. A screw 39 has its stem portionpassing through a central aperture of the pivot or integral bearing body37 and engages a threaded aperture in the member 22, said screw and body37 being substantially central of the boss or head 29 of the type-bar.The screw 39 has a slotted hexagonal head tov adapt the same to beadjusted by either a wrench or a screw-driver. The screw 39 is normallyheld under tension by reason of the spring action of the member 23, andin addition to this tension or independent thereof the said screw may-beheld at its threaded end where it engages the threaded opening in themember 22. A slot 40 may extend on opposite sides of the threadedopening for the screw, and a part of the member 22 may be cut away atone side of said opening, as at ll, to form a yielding part or finger42. This yielding part will keep the screw under tension and prevent thesame from becoming loose, while the machine .is in use, and further theoriginal tight fit of the screw will be maintained. 'By rotating thescrew the member 23 may be forced toward the member 22, and will carrythe type-bar therewith in order that the wear may be taken up in case itoccurs and the type-bar forced properly against the hanger member 22.

It will be evident that by providing a hanger or a support in which asingle pivot is provided for each type-bar and in which the pivotportion is forced in the direction of wear by means located at thepivot, all liability of the type-bar to twist when operating the machinewhich may cause unevenness in the alinement is overcome; that the ribsform means providing a substantial bearing; that said hanger or supportis simple in construction and may be made by stamping the same fromsheet metal; and that effective means is provided whereby the operatingsurface between the hanger and the type-bar may be properly lubricated.

Having thus described my invention I claim as new and desire to secureby Letters Patent 1.
